The core wire 210 is electrically connected to the conductive region 22 of each circuit board 21 . The conductive region 22 at the other end of each circuit board 21 is electrically connected to the core wire 210 of the cable.

Referring to the fourth figure, the conductive ring 300 of the first embodiment of the present invention is composed of a separable conductive first half ring 310 and a second half ring 320. The first half ring 310 is provided with a first circular arc portion 311 and a first protruding portion 312 extending radially outward from one end or both ends of the first circular arc portion 311 . The second half ring 320 includes a second circular arc portion 321 and a second protruding portion 322 extending radially outward from one end or both ends of the second circular arc portion 321 .

Referring to a sixth embodiment, a conductive ring 400 according to a second embodiment of the present invention is formed by bending a conductor including an open annular portion 410 and one end or both ends of the open annular portion 410 radially.
